Abstract
In an SRAM circuit mounted in a semiconductor device, power supply voltage reduction circuits generate reduction voltage obtained by reducing an external power supply voltage. A first power supply voltage selection circuit selects one of the external power supply voltage and the reduction voltage as a drive voltage supplied to a word line driver. A second power supply voltage selection circuit selects one of the external power supply voltage and the reduction voltage as a voltage of a power supply line supplying an operating voltage to a memory cell.
